摘要： A phase difference element and a display device having the phase difference element are provided. A base film 31 of the phase difference element 30 includes, for example, a thin resin film having optical anisotropy. A slow axis AX3 of the base film 31 points in a vertical or horizontal direction, and points in a direction intersecting with a slow axis AX1 of a right-eye region 32A of the phase difference element 30 and with a slow axis AX2 of a left-eye region 32B thereof. Thus, influence due to optical anisotropy of the base film 31 is exerted on each light being transmitted by the base film 31, so that the influence is not extremely greatly exerted on only one of light corresponding to a right eye and light corresponding to a left eye, the respective light being transmitted by the base film 31.

摘要： According to the present invention, by controlling the angular distribution of the light outputted from a light guide plate to enable the angular brightness distribution of the light emitted from a backlight device to be controlled, the thickness of a liquid crystal display apparatus having the backlight device is reduced as well as the brightness is improved due to the reduction in returned light amount. Furthermore, since light is sufficiently mixed in the light guide plate, light sources with comparative large unevenness are enabled to be used.A backlight device according to the present invention includes a hole or a projection formed on the light outgoing plane of a light guide plate or the back plane opposing the light-outgoing plane, and a side face of the hole or the projection is directed roughly perpendicularly to the light-outgoing plane. Furthermore, specular reflection plates are arranged on the bottom plane and the side faces of the light guide plate. The angular distribution of light from a light source is maintained due to the roughly perpendicular side face of the hole or the projection so that the light is led within the light guide plate and outputted outside.

摘要： A light-transmitting film that has a predetermined polarization split function, in addition to a light-collecting function is provided. The index of refraction nx in a prism extension direction and the index of refraction in a prism alignment direction differ from each other. By generating a difference in the indices of refraction in the prism extension direction and the prism alignment direction orthogonal thereto, for the light incident on the light-transmitting film, the polarization component Lx oscillating in the prism extension direction and the polarization component Ly oscillating in the prism alignment direction can have different transmission characteristics. For example, by setting the index of refraction in the prism extension direction greater than the index of refraction in the prism alignment direction (nx>ny), among the light incident on the light-transmitting film, the amount of return light of the polarization component Lx oscillating in the prism extension direction is greater than that of the polarization component Ly oscillating in the prism alignment direction. In this way, not only a light-collecting function, but also a predetermined polarization split function is obtained.
